Anomaly Detection pertinent to People Analytics
Anomaly detection imparts new capabilities to the analytics space. While it elevates the analytic solution, it is equally important to do it right. It is especially challenging in the HR domain, as the HR ecosystem usually collects data from different sources. Spotting anomalies over varying systems is highly complex because it is difficult to establish relationships across data sources. This is where intelligent feature engineering & domain expertise comes into play. The domain expert is responsible for identifying relevant features related to potential pain areas based on experience and historical data. A central data repository with only the required features can mitigate the complexity and facilitate outlier detection.
Having established the importance of anomaly detection, we discuss its applicability in People Analytics. In HR management, it can be used to expose the possibility of burnout in employees. During COVID-19, the ‘work-from-home’ culture has led to longer working hours, no vacations/leaves, working on weekends. This has resulted in fatigue in the employees, thereby affecting productivity or developing health issues. Anomaly detection can highlight these potential problem areas, compelling the manager to give compulsory time-off to the employee. Apart from this, identifying the possibility of fatigue can also prevent accidents & injuries at the workplace.
Anomaly detection can vastly improve payroll-related activities in an organization. Common anomalies include duplicate employee details, employees with no tax filing details, an employee with no bank details, employee pay rates not matching their award rate, and a few more.
Further, identifying a location where the number of payroll runs is much higher than the average value can uncover the need for payroll training. An employee hitting any tax or deduction with a limit set by the business would typically show up as an anomaly.
Anomaly detection at the gross-to-net calculation level flags any significant deviations from last month’s data. These anomalies are specific to aspects of payroll or other HR-related business processes. For payroll, moving the anomaly detection up in the processing cycle can elevate the quality of payroll processing. Applying an algorithm to identify anomalies to inputs received via integration & resolve before running the payroll is one such opportunity. This will reduce the number of off-cycle payroll runs and improve the employee experience by ensuring employees are paid timely & correctly.
Similarly, the processes related to outbound interfaces present another improvement opportunity. For example, anomaly detection can be applied to ensure that a tax file consistent with the last transmission is sent out. Deviations can be manually checked to determine their correctness. This gives additional assurance to payroll teams and can prevent hefty penalties or interest in case of incorrectness.
